They have the same syntax, just some subtle differences. You can enable the
extension with driconf, and just remove the test for IsNVProgram in
r200_vertprog.c (of course it's there for a reason, depending what the vertex
program does this may or may not work correctly).
I can't really see a reason why WoW would prefer NV_vp over ARB_vp though. It is
possible it uses NV_vp only when it detects nvidia hardware (by whatever means),
or if other nv specific extensions (for instance for fragment shading) are
detected. Again, I can't see a reason why it would do this however.

As said, it seems on Macs ARB_vertex_blend is a required extension, so no help
from there...
